摘要
采用氯化亚铜沉淀法脱除锰电解液中的氯离子,通过正交试验和单因素试验考察了反应温度、反应时间、硫酸铜和铁粉用量等因素对氯离子脱除率的影响。结果表明,硫酸铜用量对氯离子脱除率的影响最大,较适宜的脱氯条件为:反应温度40℃,反应时间30min,硫酸铜用量30.0g/L,铁粉用量3.0g/L。在此条件下,氯离子的脱除率为60.8%。
Chloride ion in manganese electrolyte was removed through CuCl precipitation process.Orthogonal and single-factor experiments were employed to examine the effects of reaction temperature,reaction time,dosage of copper sulfate and powdered iron on dechlorinate.The results show that dosage of copper sulfate has a great effect on Cl-removal rate.Removal rate of Cl-is 60.8% under the appropriate conditions including reaction temperature of 40 ℃,reaction time of 30min,dosage of copper sulfate of 30.0 g/L,and dosage of powdered iron of 3.0g/L.
